' To all whom it may concern.-

Be it known that I, HARRY W. LE F VOR, a citizen of the United States,residing at Salem, in the county of Essex, State of Massachusetts,

have invented a certain new and useful Im at a single operation.

Heretofore hides have been frequently treated in machines of the generalcharacter of that shown in the patent to Franklin J. Perkins, No.746,144, dated December 8, 1903, and of the type generally known asserialtable putting-out machines. In these'machines no difficultyhasbeen experienced in working the portions of the hide which liealong thesides of g the work-table, but great difficulty has been found insatisfactorily workingthe portion of the hide which, lies'over and"about the end of the table.

My present invention provides a simple and efficient ma chine fortreating this portion as well as the sides of the hide 'at the sameoperation.

In the drawings, Figure 1 is a vertical section of a putting-out machineembodying my invention. Fig. 2 .is a detail of the pad. Fig. 3 is adetail showing the parts in a different position. I V

Referring to the drawings, the character a indicates the serialwork-tables, upon which the skins or hides are thrown to be worked.

These tables or supports are carried by the hide upon the tables bymeans of the wellknown weighted levers j and 7c and toggles Z and m andserve to work the sides of the hide or skin on the work-support as itpasses'between the pairs of operating-rolls." The operating-rolls,endless belt, and other moving parts are given proper motions in thewell All of the parts of the machine so far described are old and formno part of my invention. It is therefore unnecessary to describe theseparts with greater particularity.

In order that the portion of thehide or skin which lies over the end ofthe work-support may be thoroughly worked or put out, I provide thefollowing mechanism, which operates upon the skin or hide prior to thetime when,

it is taken up by the table and before it passes between the two pairsof operating-rolls mentioned above. sentially, in an auxiliary operatingtool 5 and a work-support or pad, upon which the skin or hide is placedfor the preliminary operation. This pad is composed of two halves 3 and4and pivoted at 1 and 2 to suitable portions of the frame a of themachine.

When the work-table a, attached tothe end- I less belt 6, reaches apoint such that the end of the work-table strikes the underside of thetwo halves 3 and 40f the pad (see Fig. 3,) it forces the -two halves toswing about their pivots 1 and 2 and open up or separate, thus allowingthe work-table to pass through and upward between the pairs ofoperating-rolls f g and I i. two halves 3 and 4 of the pad it picks upthe skin from the pad and carries it upward to be treated by the otheroperating-rolls. When the work-table has passed between the halves 3 and4 of the pad, they fall back into place by reasonof their'weight and areready to receive another hide or skin. The halves 3 and 4 of the pad aremade up of a foundation of wood or metal QOVGY'QdlWilJh feltand leatheror. other suitable materials, as may be desired, to form aslightly-yielding surface upon which the hide may be supported duringthe preliminary workingoperation.

"I make the leather covering of the half 4 as This mechanism. consists,es-

As the table passes between the The upper face of the two halves 3 and 4of the pad when the shown in Fig. 2, with its inner edge skived offthin, so that a flap 41 is formed, which rests upon the proximateportion of the half 3 when the halves are in the operative position. Theother half 3 is completely covered with the leather over the top andside next to the half 4, as shown at 32 and 33. After the hide has beentreated the operatingtool is moved to another position, as will behereinafter later described. Considerable pressure is exerted upon thetwo halves 3 and 4 of this pad by the operating-tool 5, and if nosupport other than the pivots about which they move were provided theymight become wedged together, so that they would not separate readilywhen necessary. I have, therefore, provided projections 31 and 47,attached to the frame of the machine, which engage the ribs 34 and 44 onthe ends of the halves 3 and 4, as shown in Fig. 2, and take thepressure applied to the hide-supporting pad, thus obviating all dangerof the parts becoming wedged. In order that the skin may not slip uponthe pad during the process of working, I provide a clamp 8, which isattached to an extension 61 of the arm 6. This clamp 8 is made up of apair of clamp-bars 81 and 82. The clamp-bar 82 is bolted directly to theends of the extensions 61 on the arm 6 and has a rounded lower edgewhich holds the hide firmly against the upper surface of the half 4 ofthe hide-supporting pad. The other clamp-bar 82 has its surface slightlybeveled, as shown at 83, and this surface presses the hide against theback side of the half 4 of the hide-supporting pad. By the use of thetwo clamp-bars 81 and 82 the hide is held in two places against the padand all danger of slipping is avoided.

In order that the operating-tool 5 may be out of the path of thework-table when it is no longer in use, I provide alever-arm 9, fast tothe shaft 7, upon which are mounted the two arms 6, which carry theoperating-tool 5. This arm 9 is connected by a link 11 to one end of acam-lever 12, which is pivoted at 13 to the frame a of the machine. Thelower end of the cam-lever 12 is provided with a roller 14, whichtravels in the slot 15 of the cam 16, fast upon the shaft 17. The slot15 in the cam 16 is so laid out that the operating-tool 5 is held out ofcontact with the hide on the pad and out of the path of movement of thework-table for a time suflicient to allow the operator to place a freshhide upon the pad, when the operating-roll is lowered by the cam to itsoperative position, where it is held for a sufficient length of time towork the hide, when it is again lifted by the cam to permit the movementof the next work-table up between the halves of the pad and to permitthe operator to place upon the pad the next skin or hide.

In order that the operating-tool 5 may be given the proper rotationnecessary to work the skin, a gear 17 is placed upon the end of theshaft of the operating-tool and meshes with another gear 18, loose onthe shaft 7, about which the o iieratiug-tool 5 revolves when it ismoved upward out of its operative position. The gear 18 in turn mesheswith gear 19 on the shaft 1. The gear 19 has a sprocket 20 on its hub,and the two are loose on the shaft 1 and are driven by a chain 21 from asprocket on the main shaft 22 of the machine. By this means drivingapparatus for the operating-tool is provided, so that the operating-toolis kept in motion no matter what position it is in with regard to theshaft 7, about which it revolves.
